Although not considered a knife, the JB2 makes for a no joking around emergency tool. The general shape appears to have been inspired by similar looking Strider knives and is confirmed by the Strider logo. The main functionality is the 270 degree cutting hook. The opening is smaller than some other designs to prevent accidental snags, yet is plenty big enough to get heavy webbing inside. Once inside you want to make sure and keep the blade moving along the material to get a nice quick cut. Despite being pretty darn sharp, using it in a chopping only motion will not give great results. It is easy to miss, however there is a carbide glass breaker on the bottom for making short work out of windows. To cut down on weight, cuts were made into the frame which were done in a clever manner to form tools. There are holes to create an oxygen tank wrench and a slip wrench area for 3 hex sizes. At the end are slots for securing the strap that connects to the supplied pouch and a lanyard hole. The pouch design is functional, but my main concern is if you let the SRB flop down upon release, it can cover the glass breaker. Thus if possible I recommend grabbing both the handle and the SRB in your fist to make sure it doesn't get in the way of emergency functionality. The JB2 is compact and the weight is fairly low, but as a downside the grip isn't the most comfortable due to the whole piece being thin. It is plenty functional, just not a cushy ride. If in the market for a low profile yet full business shroudcutter, be sure and check out the JB2. It works great mounted on your kit or in your vehicle.
